Villain made from heroes

Hosu attack begins

Izuku heard Kurogiri's voice telling him about Stain joining the League.

The idea of having the hero killer join the league sounded great but he didn't know if the Hero Killer would join due to his ideal.

Izuku was selling his hero notes to the hero killer but having him as a teammate was a strange idea.

The Hero Killer turned to the young boy, "So these are the people who you are with Midoriya, anyways you what is your conviction?"

Stain turned to face Tomura as he responded, "it's quite simple, I want to kill All Might and destroy this hero society."

Stain began to show disdain to that response which he was given before turning to Izuku, "Kid, I know that you dislike heroes for their lies, why do you stay with them?"

Izuku knew that both he and Stain didn't like heroes yet in truth he didn't believe that their goals despite being similar were ever going to intervene together, both shall go on their separate ways.

Izuku turned to view Tomura as he responded to Stain's question, "They can help me with my goals."

Stain listened to the answer before looking at Shigaraki, "well, I'll think about it, if they can help you they might help me, you take me back to Hosu, I need to finish my job."

Kurogiri then opened two portals, one near Stain and one near Izuku, "Midoriya, change into your costume will you."

Izuku entered through his portal at which point the other three villains went through the other one onto a water tower.

Shigaraki angrily asked the hero killer a question before he could leave, "when can we expect an answer?"

"When I have time to think, the boy seems to be the only one of you with a true conviction while you on the other hand don't seem to have a true convection," Stain responded looking at how the leader would answer.

This angered Shigaraki as he heard another portal open at which Izuku came out in his green hoodie and mask Stain turned to ask, "why did he put that on?" 

"Yeah, even I want to know why?" Izuku wondered

Kurogiri turned to face the hero killer, "I want young Midoriya here to join you as you finish your task here."

Stain didn't bother to argue against it since the young teen is the only one he didn't dislike as he turned to face Izuku, "come along boy."

With that, the hero killer then began to jump off the building while being followed by Midoriya.

when the two were at a strong distance away Tomura turned to Kurogiri and asked, "Why did you have Izuku follow him?"

"I know you Tomura, you will be angered at what he's done so you will Nomus after him. I couldn't let you attack him before we get his answer, so Midoriya is a safeguard to keep him alive."

"Very well then, ask sensei to give me some Nomus for the city," And with that Tomura and Kurogiri, both open portals to bring in three nomus to attack the city while Izuku and the hero killer go after the remaining heroes in the city.

...

As both Stain and Izuku jumped off buildings the green teen was lagging behind the killer as he fell on to the floor but thanks to his regeneration quirk he used his power quirk to jump again back into the roofs but unknown to him he brought the attention of the hero in training Shoto.

"Shoto, quickly come on," Endeavor roared, yet the young hero in training felt the right thing was to follow the figure.

Quickly the young student noticed the green hooded boy remembering him from the attack on the USJ which caused him to follow.

When Izuku was able to rejoin Stain he saw him in a fight against the hero Native slashing the hero licked the blade paralyzing him.

Izuku saw the way in which Stain fought noticing the action leading him to know the Hero Killer's quirk.

'so his quirk involves blood'

Just when Stain placed the hero in a weak position ready to kill Izuku noticed a boy who looked like Ingenium run by gaining the attention of Stain, "Stain, I am here for revenge"

After hearing this Izuku powered himself at which point he tackles the boy to the ground.

When on the floor Izuku took the helmet away only to see the guy to be Iida from UA.

Once Izuku saw his face he was shocked as he knew rage and the young student was quite rageful which confused him, "You're from UA, what are you doing here?"

Iida turned to see his attacker, "you're from the USJ, are you working with him, I will also take you down."

"Kid watch out!" Just as Izuku heard the hero killer he turned his head up to view a shard of ice heading his way which caused him to jump away.

Iida turned to see the source of the ice only to see his classmate, "What are you doing here Shoto!"

the young protege of Endeavor, here, Izuku began to wonder what he should do at this moment.
